Best time to go on a road trip from St Louis to Yellowstone

You can embark on a road trip from St Louis to Yellowstone at any time of the year since the route is rather straightforward.

However, once you consider the fact that there are several national parks and forests that you'd love to see on the way, the best time to travel would be in summer between June and September with temperatures often around 70 degrees Fahrenheit.

You'll need to be prepared for wintery conditions if you make this trip across the Rockies in the colder months.

Winter would also be a great time to visit Yellowstone, as it's usually beautiful at this time of the year, as long as you pack appropriate winter gear to brave the cold. The temperatures can go down to 20 degrees Fahrenheit December through February.

In addition, the park is usually deserted at this time of the year, so if you aren't a fan of crowds, you can travel in the winter. Who knows? You might fall in love with winter hiking and snowboarding - just make sure to check road and weather warnings, and be aware that the park closes completely for a few days at either end of the winter season.
